Don’t be one of the millions of people suffering from vitamin D deficiency. Instead, make sure you’re getting the right amount of highly absorbable vitamin D3 today with Zahler Vitamin D3 50,000. Made from vitamin D3 or cholecalciferol, the type made naturally by the human body, this preferred form of vitamin D is known for its outstanding health benefits. These benefits include support for muscle health, bone density and strength, healthy blood sugar levels already within the normal range, immune function, heart health and more. Although vitamin D is produced by the body when the skin absorbs sunlight, many of us don’t get enough sun exposure due to climate, indoor working conditions or time of year. With 50,000 IU of vitamin D3 per serving, these capsules will make sure you’re getting an abundant amount of the “sunshine vitamin” every day.

Q: Why are some vitamin D products measured in IU while others are in mcg?

Due to changes in FDA labeling guidelines, vitamin D amounts must now be listed in micrograms (mcg) on supplement facts and nutrition labels instead of international units (IU). Although these new guidelines were issued in 2016, updates weren't required until June 2020.

At Swanson, we began updating our labels in early 2017. You will see a mixture of both IU and mcg as our national brand partners complete this process.

Q: Did my vitamin D supplement change?

A: You may have noticed a change in the daily value percentage on your favorite vitamin D product, but that doesn't mean your product changed. The FDA increased the recommended daily intake (RDA) of vitamin D, which means the same product with the same ingredient amounts fulfills a lower percentage of the RDA than it prior to the change.

Q: How much vitamin D do I need each day?

In 2016, the Food and Nutrition Board increased the Recommended Dietary Allowance (RDA) of vitamin D for most adults from 10 mcg (400 IU) to 15 mcg (600 IU) per day, and 20 mcg (800 IU) for ages 70+.

Some doctors and nutritionists recommend higher daily vitamin D intakes, especially for those at risk for having low levels. The Vitamin D Council, an organization dedicated to raising awareness about vitamin D, recommends average adults supplement with 125 mcg (5,000 IU) of vitamin D daily. Talk with your doctor about your individual needs.
